[0012] A method for using a synthetic fiber strength tensile testing device is also provided, which is used to operate a synthetic fiber strength tensile testing device, comprising the following steps: S1: The synthetic fiber strip is clamped between two sets of fiber clamps, and then the two sets of sleeves and inner tubes are closed. During the movement of the lifting assembly, the synthetic fiber strip is driven to stretch in the locked space; S2: When the lifting assembly moves downward, several groups of inclined lifting blocks are buckled to the lower side of the semicircular buckle. When unlocked, it moves downward and then upward to automatically unlock the inner tube fixation. S3: In a sealed state, high-temperature or low-temperature gas can be added to the two sets of sleeves and inner tubes through two sets of air port connectors to perform strength tensile testing of the fabric in harsh environments. Subsequently, the fan motor drives the fan head to blow the flying fibers to the inside of the sink box.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Clamp the synthetic fiber strip between two sets of fiber clamps, and then rotate the two sets of sleeves and inner tubes along the fixed column to close them together. The two sets of locks lock them together. When the two sets of inner tubes overlap, the height of the sleeves can be extended. They are buckled in the fixed assembly with semicircular buckles and driven during the movement of the lifting assembly, so that the synthetic fiber strip can be stretched in the locked space to prevent the fiber waste generated when the lifting assembly stretches or breaks the synthetic fiber strip.

[0014] 2. By starting the drive motor to rotate the threaded rod, the threaded movable seat is driven to move up and down along the fixed sleeve, thereby driving the air intake assembly and fixed assembly on the movable seat to move up and down. The stretching of the synthetic fiber strip is combined with the tensile strength detection work of Gefran's wide temperature sensor, and the feedback is displayed on the fiber tensile tester.

[0015] 3. When the lifting assembly moves downward, it drives the fixed ring to be sleeved on the outside of the two groups of semicircular buckles, and the sealing cover ring is inserted into the inner tube and fits the inner wall. As it moves downward, several groups of oblique lifting blocks will be pushed by the inclined semicircular buckles and move toward the inside of the movable groove. The elastic belt is stretched by the connected U-shaped sleeve until the unlocking block contacts the semicircular buckle, and it will be lifted up by the unlocking block. At this time, the elastic stretched elastic belt pushes the oblique lifting block on the positioning slider to the lower side of the semicircular buckle, and the inner tube can be lifted by the lifting assembly to meet the position change and sealing work of the synthetic fiber strip when stretched, and cooperate with the air intake assembly to change the internal temperature.

[0016] 4. To unlock, move the semicircular buckle and the lower inclined surface of the unlocking block downward, and push the positioning slider and the elastic band again until the unlocking block reaches the upper inclined position. Then move upward again, and the unlocking block and the positioning slider are pushed into the movable groove again. At this time, the semicircular buckle is detached from the lower position of the inclined lifting block, automatically unlocking the inner tube fixation.

[0017] 5. In a sealed state, high-temperature or low-temperature gas can be added to the two sets of sleeves and inner tubes through two sets of air port joints, so as to test the strength tensile test of the synthetic fiber strips of the new material in a harsh environment of high temperature or low temperature, and complete the strength attenuation rate of different environments under the test scene simulation. In addition, when the fan head is rotated by the fan motor, the flying fibers are blown to the inside of the sink box. After contacting the water source in the sink box, they stick to the water, avoiding the harm of fiber waste to the human body when it is opened. BRIEF DESCRIPTION OF THE DRAWINGS

The upper circular hole 56 corresponds to the inner side of the two overlapping sets of sleeves 33 , and the lower circular hole 57 is connected to the inside of the water tank box 7 . The circular sleeve 510 covers the outside of the cross column 58 .

[0030] In a sealed state, high-temperature or low-temperature gas can be added into the two sets of sleeves 33 and the inner tube 35 through two sets of air port joints 54, so as to test the strength tensile test of the synthetic fiber strips 512 of the new material under high-temperature or low-temperature harsh environments, and complete the strength attenuation rate of different environments under the test scene simulation. In addition, when the fan head 53 is driven to rotate by the fan motor 52, the flying fibers are blown to the inside of the sink box 7, and after coming into contact with the water source in the sink box 7, they stick to the water, avoiding the damage of fiber waste to the human body when it is opened.

As it moves downward, several groups of inclined lifting blocks 66 will be pushed by the inclined semicircular buckles 37 to move toward the inside of the movable groove 64, and the elastic belt 69 is stretched by the connected U-shaped sleeve 68. When the locking nut 67 is unlocked, the locking nut 67 is unlocked, and the locking nut 67 is unlocked. When the locking nut 67 is unlocked, the locking nut 67 is unlocked, and the locking nut 67 is unlocked. When the locking nut 67 is unlocked, the locking nut 67 is unlocked, and the locking nut 65 is unlocked. In the movable groove 64, the semicircular buckle 37 is now separated from the lower side of the inclined lifting block 66, and is automatically unlocked to fix the inner tube 35; and in the sealed state, high-temperature or low-temperature gas can be added to the two sets of sleeves 33 and the inner tube 35 through the two sets of air port joints 54, so as to test the strength tensile test of the synthetic fiber strips 512 of the new material under high-temperature or low-temperature harsh environments, and complete the strength attenuation rate of different environments under the test scene simulation. In addition, when the fan head 53 is driven to rotate by the fan motor 52, the flying fibers are blown to the inside of the sink box 7, and after contacting the water source in the sink box 7, they stick to the water, avoiding the damage of fiber waste to the human body when opening.
